v1.8.7

• Added Lingo::Attendee::LsiFilter to correlate semantically related terms
  (LSI) over the
  "corpus" of all files processed during a single program invocation; requires
  lsi4r which in turn requires
  rb-gsl. [EXPERIMENTAL: Interface may
  be changed or removed in next release.]
• Added Lingo::Attendee::HalFilter to correlate semantically related terms
  (HAL) over
  individual documents; requires hal4r
  which in turn requires rb-gsl.
  [EXPERIMENTAL: Interface may be changed or removed in next release.]
• Added Lingo::Attendee::AnalysisFilter and associated lingoctl tooling.
• Multiword dictionaries can now identify hyphenated variants (e.g.
  automatic data-processing); set hyphenate: true in the
  dictionary config.
• Lingo::Attendee::Tokenizer no longer considers hyphens at word edges as part
  of the word. As a consequence, Lingo::Attendee::Dehyphenizer has been
  dropped.
• Dropped Lingo::Attendee::NonewordFilter; use Lingo::Attendee::VectorFilter
  with option lexicals: '\?' instead.
• Lingo::Attendee::TextReader and Lingo::Attendee::TextWriter learned
  encoding option to read/write text that is not UTF-8 encoded;
  configuration files and dictionaries still need to be UTF-8, though.
• Lingo::Attendee::TextReader and Lingo::Attendee::TextWriter learned to
  read/write Gzip-compressed files (file extension .gz or .gzip).
• Lingo::Attendee::Sequencer learned to recognize 0 in the pattern to match
  number tokens.
• Fixed Lingo::Attendee::TextReader to recognize BOM in input files; does not
  apply to input read from STDIN.
• Fixed regression introduced in 1.8.6 where Lingo::Attendee::Debugger would
  no longer work immediately behind Lingo::Attendee::TextReader.
• Fixed lingoctl copy commands when overwriting existing files.
• Refactored Lingo::Database::Crypter into a module.
• JRuby 9000 compatibility.
